ABSTRACT:
The invention comprises a built-up roof composite that is used upon seamed roof substrates. The composite has a membrane that is simultaneously formed and affixed to a base sheet adhered to the roof substrate. The membrane comprises a sheet of heat-resistant, non-woven polyester sandwiched between layers of asphalt. The upper asphalt layer is caused to flow through the polyester and meld with the lower layer of asphalt to form a homogeneous membrane.
